Abstract (en)

[origin: EP2365357A1] Methods and systems are provided for inducing seismic energy waves in a subterranean formation. More specifically, seismic transducers (200) are provided that incorporate enhanced seismic baseplates (230). In certain embodiments, baseplates (230) comprise certain enhancements (233) such as having a perimeter in the shape of a polygon, such as, a hexagon or an octagon. In other embodiments, the perimeter (233) of the baseplate may take the form of a polygon having n sides, where n is any integer greater than 4. Advantages of such baseplate enhancements include, but are not limited to, a reduction of baseplate harmonics or ringing, enhanced baseplate strength so as to reduce baseplate fatigue or failure, a reduction of baseplate flexure, and a consequent reduction of baseplate weight resulting in a more responsive baseplate. These advantages ultimately translate to improved seismic surveys, having higher resolution of the formations surveyed and resulting in surveys reaching greater depths.
